A Comparative and Analytical Study of the Values of some Biomechanical Variables of Defensive Skill in the Volleyball Court between Positions 1 and 5

Abstract

         Most team players should be highly skilled at defending in the court, which will enhance their defensive skills and lead to better results. The importance of this research is evident in highlighting the most important factors that lead to improving the players’ defensive skill. It is also necessary to highlight the differences between the (positions1) and (position 5) in order to achieve the best results. The lack of precise knowledge of the requirements for performing the defensive skill and its biomechanical variables leads to a weakness in the preparation of players, indicating a deficiency in their skillful performance in defense. This explains the difficulty in correcting errors in the advanced stages. The research aimed to identify the values ​​of some biomechanical variables when performing the defensive skill between the positions (1, 5), as well as to identify the differences in the values ​​of some biomechanical variables when performing the defense between the positions (1,5). The researchers hypothesized that there are significant differences in the values ​​of some biomechanical variables when performing defending skills between the positions (1,5). The research community consists of the Southern Gas Sports Club, from February 30, 2024 to April 12, 2024 at the Sports Hall in Al-Zubair. The researchers’ conclusions indicate the differences in the values ​​of the variable hip joint angle at the moment of contact with the ball between moving and stationary defense, in favor of moving defense, and for both positions (1-5). The most important recommendation was to emphasize decreasing the angle between the arms and the torso so that the ball rebounds appropriately according to the mechanical principles.
